Account Proof

Prove account ownership of a Flow account
Flow provides a way for dApps to ask for users' signatures when they connect a wallet and verify account ownership. For more information, refer to Account Proof on Flow.
Currently Blocto self-custody accounts generate this signature slightly differently and needs an alternative way to verify ownership.
import { AppUtils } from '@blocto/fcl'
const isSignatureValid = await AppUtils.verifyAccountProof(
appIdentifier,
{
address,
nonce,
signatures,
},
{
fclCryptoContract: BLOCTO_FCLCRYPTO_CONTRACT_ADDRESS
}
)
The addresses of the Blocto FCLCrypto contract BLOCTO_FCLCRYPTO_CONTRACT_ADDRESS can be found here:
